Cache autocomplete_sources on the frontend
What does this MR do and why?
This is an initial iteration to improve caching for the autocomplete_sources endpoint. It sets expires_in to 3 minutes if cache_autocomplete_sources is enabled.
As a second iteration after this is completed we can work on implementing ETags to allow longer cache expiry.
Screenshots or screen recordings
